THE EMBRYONIC AND LARVAL DEVELOPMENT OF CAPOETA TRUTTA (HECKEL, 1843)
MetadataShow full item record
The embryonic and larval development of Capoeta trutta (Heckel, 1843) were observed after artificial fertilization. Eggs were obtained from females and milt was obtained from males matured by using abdominal massage naturally. Fertilized eggs were kept in lake water at 24-26 degrees C. The perivitelline space formed 30 min after insemination. The diameter of the fertilized eggs ranged from 0.63 to 1.95 mm. The first cleavage occurred at 1.5-2 h, the morula began at 5 h, the blastula was observed at 9 h. An embryonic body formation was formed from the embryonic shield and also some somites were observed 10-12 h after insemination. The first hatching was occurred 60 h after insemination. Larval development of C. trutta was observed 96-240 h after insemination.
